A method for the production of a tool receiving device is disclosed. The method includes positioning at least one sleeve with at least one driving web on an outer circumferential surface of at least one component of a forming tool, inserting the at least one component of the forming tool into a cylindrical bore of the tool receiving device such that an outer circumferential surface of the sleeve bears on an inner circumferential surface of the tool receiving device, and exerting a force on the outer circumferential surface of the tool receiving device for forming the tool receiving device and for forming at least a partial region of the inner circumferential surface of the tool receiving device, on which bears the outer circumferential surface of the sleeve, so that a non-positive and positive locking connection is produced between the inner circumferential surface of the tool receiving device and the sleeve.

An impact tool head is provided and configured to be disposed on a front end of an impact tool. The impact tool head includes: a rod body and a flange radially protruding from the rod body. The flange includes an inclined flat surface facing toward the front end and an outermost peripheral edge. A contact position is defined as a position where the inclined flat surface contact with at least one projection of the impact tool. Wherein each of the at least one projection is a ball member, and as viewed in the axial direction, a ratio of a distance between the contact position and the outermost peripheral edge to a radius of the at least one projection is between 0.1 and 0.6.
